sssd-廣告在喘息中

我在serverfault上執行了一個類似的問題，但我有一個更適合這裡的後續問題，以我的謙虛（可能不知情）的觀點。

我一直在嘗試針對公司 AD（Windows 2008 伺服器）驗證我的 Debian Wheezy 伺服器中的使用者。

主要挑戰是此 AD 不提供任何 Unix 屬性（uid、gid、homedir、shell）。我通過使用 sssd 及其備份機制繞過了 homedir 和 shell。但是，我目前卡在uid，gid上。

當我嘗試使用配置進行同步時（我將其縮減為相關部分）

id_provider = ad
access_provider = ad
auth_provider = krb5
chpass_provider = krb5
ldap_schema = ad
ldap_id_mapping = true
debug_level = 7

我收到以下錯誤：

我如何在 Debian Wheezy 上獲得 sssd 的 sssd 廣告提供商？我已經看到了很多使用它的例子。它真的不包含在 wheezy 發行版中嗎？我可以通過某種方式使用 ldap 提供程序來解決它嗎？還是我必須弄亂我的伺服器並將不穩定的儲存庫添加到我的源中？

來自測試的版本 1.11.7-2 在生產環境中對我有用。

您不需要從 stable 升級整個系統，只需添加一個測試儲存庫：

deb http://ftp.uk.debian.org/debian/ testing main contrib non-free
deb http://ftp.uk.debian.org/debian/ testing-updates main contrib non-free

您可能需要apt說明您更喜歡穩定版。為此，您可以將此部分添加到文件中，例如/etc/apt/apt.conf.d/00local

APT {
   Default-Release "stable";
   // Cache-Limit "50000000";  // only if needed
};

然後執行aptitude update，你應該會發現aptitude install -t testing sssd-ad提供安裝和升級 sssd 等。

為了完整起見，這裡是我的（已編輯）sssd.conf
